Bug Description

This is very basic and simple, yet very important feature that should be loaded by default. Until a week or so before the final release of Saucy, everything was fine but then, suddenly, I noticed the Power Manager is not running when I start my machine and login to Lubuntu and it seems this is a last minute change.

If I go to Menu > Preferences > Power Manager, I get this message:

"Xfce4 Power Manager is not running, do you want to launch it now?"

Please note that I am not converting people in Real Life to Linux. People who have been using Windows XP for their entire life. If this bug will remain for a long time, I will have hard time and that will never make them happy which means I have to find another alternative for Lubuntu.

I also experienced this problem on upgrade from 13.04 to 13.10, and the above work-around fixed it. I also had a problem where xscreensaver wasn't working either (wouldn't ask for a password after waking from suspend), and I had to set xscreensaver as the default screensaver, too.

Another solution is to open Preferences --> Default applications for LXSession, then go to the autostart tab and here change the option "Disable autostarted applications" from the default "config-only" to "no". You may need to change the settings for laptop-mode from "no"to "yes". (settings tab).

Note that you need to disable "network" from Prefereces-->Desktop Session Settings or you will have two nm-applet running at the same 1time.

I think the new default application manager introduced on 13.10 is a bit confusing but if it is the new way of configuring session isn't
better to trow out the "classic" Desktop session Settings entry on menu?

I was troubleshooting another Autostart problem (with SpiderOak online backup) and was looking for Preferences-->Desktop Session Settings, but find that it is not present.

My current assumption is that Preferences-->Default Applications for LXSession somehow incorporates and replaces Desktop Session Settings, but I have not figured out how to use it for that purpose yet.

Or its absence is also a bug.

This machine has a fresh full install of Saucy. Federico, did you *upgrade* to Saucy and perhaps thereby preserve Desktop Session Settings?

Lubuntu 13.10 and newer versions are not reading this folder for autostart applications, so a user should add the xcfe4-power-manager command in .config/lxsession/Lubuntu/autostart file if he/she wants the power-manager to start properly.

I think that Lubntu devs should think about and create this file and add it to .config/lxsession/Lubuntu/autostart by default.

32 days now or so and there is no real action on this bug but I guess sooner or later, the Developers will pay attention to this one because, IMHO, this one is important and shouldn't be ignored or treated as Low Priority but that is just my opinion and after all, I am not a Dev :)

Sorry for the typo on Comment #20.
It appears that the bug report (Bug #1326045) I just filed for Lubuntu 14.04 LTS Desktop AMD64 has the same issue.
The matter has not really been resolved, and Lubuntu 14.04 LTS still has the issue.

I have a similar problem on Ubunto 14.04 LTS where I installed XFCE :
Launching the Power manager does nothing then after a few seconds a dialog display:

"Unable to get configuration information from xfce power manager: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

Launching "xfce4-power-manager-settings" has the same result.
Launching "sudo xfce4-power-manager-settings" asks me "Xfce4 Power Manager is not running, do you want to launch it now?"

Following up on my own comment, I do note that on a laptop I just checked (also running Lubuntu 14.04.1), 'OnlyShowIn=XFCE' is present but power manager starts anyway.

The only speculation I have about why power manager works on the laptop and not on the desktop is that somewhere (in the lxsession settings perhaps) there is a profile setting for desktop vs laptop, which may influence the outcome here.
